In Hamlet, Shakespeare has Hamlet tell his girl Ophelia to “Get Thee To A Nunnery!” This was Elizabethan slang for a brothel. But, actual real-life nunneries in those days often had a large population of “fallen women” who couldn’t look forward to any home and family in the future. So, it really was a collection of former whores. These nuns would typically be occupied in some useful social service, as a hospital, a school, an orphanage, or the like.
Today we have a genre of “born-again slores,” which is the way it has been since the days of Shakespeare, although perhaps a lot more numerous these days. They should be sent to a nunnery — preferably, a real-life Christian nunnery, which you don’t see much of anymore. There they could do something useful, rather than just being a blight on society. They could even bring their single-mom children, to be raised by the Nuns. I don’t see why not. Unfortunately, the spread of the Welfare State has reduced the need for charitable institutions run by nuns.
But, don’t marry them!
